Answer 1

Frame has 2 behaviors: frame as document element (like div or another DOM element) and frame as window element (like global window object). So if you want to remove iframe from DOM tree you have to work with iframe like with DOM element

function remove(){
 var frame = document.getElementById("upload_iframe");
 frame.parentNode.removeChild(frame);
}

A way I've been doing it (since I have a large amount of iframes) is using jQuery,

$('iframe').remove()

or in the case of only one iframe you can remove it using its ID, still with jQuery

$('#iframeID').remove()
